As the Facebook boys started dealing increasingly with real
business professionals, a reputation for rambunctiousness spread
throughout the valley. "It's Lord of the Flies over there," one
executive told an executive recruiter. Zuckerberg had to be
careful which business card he handed out at meetings. He had two
sets. One simply identified him as "CEO." The other: "I'm
CEO...bitch!"

One of the crew's edgiest pranks in those days was a presentation
made to the blue-chip venture-capital firm Sequoia Capital, known
in the Valley for a certain humorlessness. Sequoia éminence grise
and consummate power player Michael Moritz had been on Plaxo's
board. Parker saw him as having contributed to his downfall.
"There was no way we were ever going to take money from Sequoia,
given what they'd done to me," says Parker. The firm wanted to
invest in Facebook, so as a joke the boys offered to pitch the
partners a Zuckerberg side project called Wirehog, a peer-to-peer
file-sharing program.

Zuckerberg and another partner showed up deliberately late for an
8 a.m. meeting, in their pajamas. They didn't even make a pitch
for Wirehog. Zuckerberg showed a PowerPoint presentation David
Letterman-style: "The Top Ten Reasons You Should Not Invest in
Wirehog." It started out almost seriously. "The number 10 reason
not to invest in Wirehog: we have no revenue." Number 9: "We will
probably get sued by the music industry." By the final few points
it was unashamedly rude. Number 3: "We showed up at your office
late in our pajamas." Number 2: "Because Sean Parker is
involved." And the number one reason Sequoia should not invest in
Wirehog: "We're only here because [a Sequoia partner] told us to
come." The partners seemed to listen respectfully, recalls
Zuckerberg, who says he now regrets the incident. "I assume we
really offended them and now I feel really bad about that."
